To all whom it may concern:

Be it known'that I, ERASTUS WoonwAnn,

of Somerville, in the'countyof Middlesex and State of Massachusetts, have invented mechanisms for operating the type-head and the inking pad.

Another essential feature of this device is the provision of an automatic work-supporting table which will automatically adapt itself to any thickness of material.

Another feature is the provision of automatic mechanism for covering the inking device to excludedirt and dust and prevent evaporation and adapted to automatically uncover said inking mechanism only when it is necessary to ink the type.

Another feature of the inking device is the utilization of an absorbent .pad which carries the ink and which contacts with the inking roll in order to prevent an excess of ink from being fed to said roll.

In the accompanying drawings which illustrate a construction embodying my invention, Figure 1 is a front elevation of the machine with the type head removedshowing the parts innormal or non-operating position. Fig. 2 is an end elevation of .Fig. 1 showing the type head, inking mechanism and automatic table in normal position. Fig. '3 isan opposite end elevation of Fig. 1 showing the clutch or driving mechanism with the driving pulley removed. Fig. 4 is a vertical sectional'view through the auto matic work-supporting table. sectional view on line 5-5 Fig. 1 showing the mechanism for automatically controlling the adjustment of the work-supporting table. Fig. 6 is a sectional view on the line 66 Fig. 1 looking in the direction of the arrow and showing the operation of ink-ing the type. V Fig. 7 is a similar view to Fig. 6 showing the position of the parts with the type-head about to make an impression. Fig. 8 is a front elevation of the'inking device. Fig. 9 is a top plan view of same.

Fig. 10 is a cross sectional view through Fig. 5 is a,

the center of Fig. 9. .Figs. 11 and 12 are detail views to be hereinafter described.

Like letters of reference refer to likeparts throughout, the several views.

A is thebed of the machine and carriesthe postA and main frame C. Mounted in the bearings C in the upper part of frame G is a rock shaft D carrying on its outer end the yoke arm D secured thereto by the screw D This arm D carries mounted on its outer'end the inking mechanism E. This rock shaft D is operated by the cam lever D which carries the roll I) operating in the cam track D on one face of cam F.

'The cam F is mounted on the driving shaft B which is mounted in bearings A and B The rock shaft G is mounted in I the bearings C in the lower part of the frame C and carries the lever or type carrier G. secured thereto by the screw G The type head J is secured by the clamp screw J 2 to the outer end of the lever G and the rock shaft G is operated by the cam lever G which carries the roll Gr which operates in the cam track G in the opposite face of the cam F. Mounted on the extension H of the bed A is a platen or worksupporting table II (Figs. 4 and 5) and this table H is mounted on the spiral screw H which is vertically movable in said ex-' tension H. p

H 'is a pin mounted in a hole in the extension H which prevents the table from rotating.

\l i The lower end of the screw H is piv- .oted at S to'one end of lever S which carries a pin S to which is secured the lower end of the spring H the opposite end of support for the table when the impression is being made. Mounted within the extension H and over the screw H is a nutH which is rotatable within said extension.

H is a collar loosely mounted over the screw H and carries the armI-I normally held against the stop H by spring H This arm H carries the pin H which isreciprocally movable in the hole H in the extension H andhas a beveled notch or recess H in which is mounted one end of a lock lever K which is pivoted at K in the extensipn H; the opposite end of said lever is pivotally connected at K within'the yoke K into which yoke K is adjustably thread- I between the bed A and the adjustable nut or stop K to hold said rod K outward and the lock lever K in the position shown in Fig. 5 whereby the projection/K fric tionally engages the nut H to'lock the same against rotation, The squared end of rod K is for the purpose of. adjusting the sleeve K" and thereby regulating the time during which the roll K engages the cam is. The cam is on the cam face K operates during a certain point in the revolution of the cam F to actuate the lever K and rod 7 K against the pressure of the spring K to move the lock lever K withdrawingthe projection K from frictional contact with the nut H to permit the same to rotate. The object of 'thus freeing the nut H is to release thetable H through spiral screw H to permit the table to be raised by the spring H a predetermined amount to give suflicient tension to obtain a clear impression. The cam is immediately releases said lever K through means heretofore described allowing the projection K to bear on the nut H which locks the table H in adjusted position.

Pivoted at M in-the. outer corner of the extension H is a cam M carrying a handle M which in the position shown in Fig. 5 does not engage with the outer end of the lock lever allowing the operation of same as heretofore described, but when it is desired to allow the table H .to move up and down without locking the samein an adjusted position, the operator moves the handle M until the cam M engages and moves the outer end of lever K through the projection K out of frictional contact with nut H.

S is a lever centrally pivoted at S to the link S pivoted on the lower side 'ofextension H, the outer end of said lever being pivoted as heretofore stated, at S -to the lower end of the spiral screw H The opposite end of said lever S is pivoted at S to the rod S which may be connected with or operated by a treadle or other suitable-device for depressing the table against the tension of spring H to permit the insertion of the work, if it is not desired to have the table adjust itself automatically as described.

The type-head J is provided with a seriesof ring type disks J rotatably mounted on a central shaft J which is journaled in the type head J. One end of the shaft J 4 profrictionally turning those of the type disks Y which are released by suitable pawls pivoted on the shaft J 6 so that the required figures or characters which are carried on the periphery of the disks may be moved into alinement for making animpression therewith.

The inking mechanism E comprises the casing E which carries a hollow supporting stem E mounted within the clamp E in the lowerend of the yoke arm D. A screw E is adapted to clamp the casing E in position on said yoke arm 1) (see Figs. 6 and 7). Journaled in the casing E is a shaft E which carries the inking roll E Mounted inside the casing and around this roll and f in contact therewith is an absorbent composition E", preferably felt, which retains or holds the ink and feeds the same to the pad One end of the shaft E projects outside of the casing E and carries screwed thereto the ratchet wheel E". This ratchet wheel E 'is adapted to be actuated by the pawl E which is pivoted at El to the arm E secured to the rock shaft G by the screw E vThe action of this pawl E on ratchet E is so timed that at each impression .of the type head the arm E will operate through said pawl E to intermittently move the ratchet E and pad roll E and thereby present a fresh inking surface on said roll to the type at each contact of said type therewith. This intermittent movement of the roll E causes the ink to be evenly fed or distributed upon said roll by the felt E which holdsthe ink latch E" (see Figs. 11 and 12). This latch E" is pivoted at E in a slotin the lower end of the hanger E, the upper end of which hanger-is loosely mounted on the hub E in the upper end of the yoke .arm D. The spring E secured to the lower end of the hanger E acts against the extension E ofthe spring latch E" to hold said latch in position within the notch E 1E and E are stops carried by hanger E on respectively opposite sides of the rib.

E on main frame C.

The operation of the shutter E is shown in Figs. 6. and 7, Fig. 6 showing the type and normally free to rotate on said shaft,

said pulley N beingheld in'position by the bushing B secured to the end of said shaft B by the pin B (see Figs. 1 and 3).

N is a sleeve securely pinned to the shaft B adjacent the inner face of the driving pulley N, said sleeve carrying an extension N upon which is mounted a vertically disposed arm N having pivoted thereto at N one end of a lever N the opposite end of said lever N 3 carrying the friction roll N pivoted thereto at N This roll N carries a dog N on its upper face which is adapted to be normally retained -adjacent to but out of frictional contact with the inside periphcry of the hubN of pulley. N. The lower face of the roll N is beveled at N and normally rests-upon the wedgeplate N which is carried by a sliding sleeve N- which is slidably mounted over the sleeve N a recess N in said sleeve straddling over the extension i on the fixed sleeve 1 2 thereby permitting a sliding movement of the sleeve N but causing the sleeve N and shaft B to ro' tate when the sleeve N is caused to rotate. A spring P is pinned at one end to the extension 1 and at the other end to the sliding sleeve N, said spring normally acting to pull the sliding sleeve N toward the pulley N; A cam strip N is secured to the sliding sleeve N", the inner face of said cam strip normally engaging with a switch plate P secured to the upper arm of Y the bell crank lever P. Lever P is pivoted at P to the lower part of post A, the lower arm of said lever P being pivotally connected with a rod C? which may be operated by a treadle or any other suitable means for operating the switch plate P torelease the cam strip N and sliding sleeve N r P is a spring which is secured at one end to the bed A and at its other end to the lower arm of the bell crank lever Pi, said spring being adapted to hold the'switch plate P against the face of the cam strip N The operation of this clutch is hereinafter more fully described. This clutch mechanism is not; claimed in this application, but is shown, described and claimed'in another application filed by me November 1st, 1909, Serial No. 525672. e

The operation of the machine is as follows: The operator places the Work or other article tobe marked onthe table H; this work may consist of either a single piece or a bunch of pieces of fabric, such as shoe linings, which are to be consecutively stamped. Vhen the operator is ready for the impression to be made, the treadle connected with the rod C is pressed moving the bell crank lever P against the pressure of thespring P which movement operates to throw the switchplate P out of contact with the cam strip N. The spring P automatically throws the sliding sleeve N toward the pulley N causing wedge plate N to lift the friction roll N untilthe dog N frictionally engages the inner periphery of the hub-N causing the sleeve N" and driving shaft B to rotate. The cam F now rotates with shaft B, the cam track D operating the roll D, said movement acting through lever D rock shaft D and yoke arm D to move the inking mechanism E outwardly from the position shown in Fig. 2 to that shown in Fig. 6. Simultaneously, the cam track G operates roll G which acts through cam lever G rock shaft G and lever G to move the type head J backward from the position shown in Fig. 2 to that shown in Fig. 6. The relative movements of the typehead J and the inking mechanism E bring the type into contact with the inking roll E, said roll having been automatically uncovered during this movement of the inking mechanism E by means of the shutter E being withdrawn through action of the hanger E which hanger has been carried mechanism E until the stop E (Fig. 6) engages the rib E- checking any further movement of said hanger while the inking mechanism E continuing its movement to the po- \1 sition shown in said Fig. 6 causes the shutter E to be withdrawn through the action of the latch E mounted in notch E holding said shutter when the stop E engages the rib E The inking roll E being exposed, the type carried by disks J 3 pressing thereon causes the type to be suitably inked. A continued movement of cam F causes the rock shafts D and G to oscillate in the opposite direction, said shaft D acting through lever G to move the type head J forward and downward until the type engages with the work making an'impression upon and marking the same (see Fig. 7) said type head being immediately lifted from contact with the work to its normal position as shown in Fig. 2. shaft D operates the yoke arm D to withdraw the inking mechanism E from the position shown in Fig. 6 to that shown in Fig. 2, the shutter E being automatically moved to cover the inking roll E during said movement through the action of hanger E when the stop E engages the rib E at the time the type is in engagement with the work. The inking mechanism now remains forward by said movement of the inking In the meantime, the rock in this position during the return of the type head J to its normal position as shown in Fig. 3. 1

\Vhen the parts have moved to the position shown in Fig. 2 after making the impression, the driving shaft B and cam F have made practically one revolution and the switch plate P engages the projecting face of cam strip N forcing the sliding sleeve N outward against the pressure of spring P withdrawing the wedge plate N from beneath the friction roll N causing the roll to drop and dog N to be thrown out of engagement with the periphery of the hub N The driving shaft B is now at rest being disconnected from the pulley N which now operates idle upon the outer end of said shaft B. Assuming a bunch of pieces has been placed on the table H by the operator to be marked: the type, upon engaging with the topmost piece, forces the table H; spiral screw H and nut H downward forcing the collar H" against the spring H at the same time moving downward the beveled pin H, the beveled surface H acting to force the outer end of the lock lever K outward, withdrawing the projection K and allowing the nut H to rotate until' the table H hasvreached a position to allow for the thickness of the bunch of pieces. During this operation the impression has been made by the type upon the upper piece on the table. Immediately before the upward or return movement of the type head the spring H acts to force the collar H and beveled pin H and nut H upward causing the beveled surface H to withdraw from the outer end of the lock lever K allowing the projection K to frictionally engage the nut H preventing the rotation of said nut and securely locking the table H against upward movement. The operator now removes the top piece which has been marked and the treadle connected with the rod C is again operated,'which as heretofore described, throws the driving pulley into connection with the driving shaft B which operates to ink the type by means of the inking mechanism E, as described, the type moving .to the position shown in Fig. 7. The removal of the marked piece leaves the piece now to be marked below the lowest position of the type, so that before the type has reached its lowest point the cam k on the cam face K on the outer periphery operates the roll K to move the rod K" and lock lever K sufficiently to Withdraw the end of said lever K from the contact with the beveled face'H. This leaves the nut H free to rotate while the spring H forces the spiral screw H and table H upward a predetermined distance or a sufficient amount to carry the upper piece to be marked a sufficient distance above the lowest position the type assumes to insure suflicient tensionfor securing a proper impression. This distance is gaged by the interval during which the cam is contacts with the roll K and holds projection I 12 out of contact with the nut H so that when the roll K isreleased or dropped by the 'cam is the projection K engages the nut H locking the table H in thepredetermined position.

The distance the table H moves upwardv can be adjusted, as heretofore described, by

'means of the squared end of the rod K which can be operated to 'turn rod K and through the sleeve K and yoke lever K change the position of the roll K and consequently the interval during which said roll contacts with the cam is. The adjust ment of the squared end of the rod 1K moves the roll K either away from or closer to the face of the cam F, so that when the roll K strikes the bevel of the cam is and rises over the apex of the cam and then returns to its r normal position, the interval of contact would be less when the roll K is adjusted farther away from the face of the cam F and nearer the apex K, Therefore the shorter the interval during which the roll K is held by the cam 70, the less the dis- J descends still farther, the type engaging.

the upper piece of stock making the impression thereon and forcing the table H down against the tension of the spring H and through the beveled surface H against the tension of the spring K Immediately upon the withdrawal of the type head the nut H is frictionallyengaged in the'manner "heretofore described locking the table H in the position in which the type has moved the same. The piece upon which the impression has been made is now removed by the operator and the remaining pieces are consecutively printed in the manner ,heretofore described.

If the operator desires to print the articles by placing the same consecutively on the table until a bunch is accumulated on the table instead of initially placing the bunch upon the table and removing the same consecutively, the operation of the parts is identical with that heretofore described with the exception that instead the table H rises the predetermined distance, but is forced downward by the type the amount which the table has moved upward plus the thickness of the stockwhich has been placed under the type.
